Calculation of the indoor gamma dose rate distribution due to building materials in the Netherlands

In this study, a model to determine the indoor absorbed dose rate in air due to building materials is applied to a representative set of 1336 Dutch dwellings of which the areas occupied by the various kinds of building material are well documented. Using a Monte Carlo method, the building material and housing data are combined with activity concentrations and densities of 90 samples of building material. From (100 000) repeated calculations according to the model, the distribution of the absorbed dose rate in Dutch livings is computed. The outcomes are compared with those of earlier national m...
